Definitions
- Night vision devices such as night vision goggles (NVG's) are well known for being able to enable a user of such a device to easily see in darkened environments. These devices are often used in military applications to enable soldiers to see without the use of extraneous visible lighting, such as flashlights, which may give away their position to the enemy.
- the NVG intensifies the available low-level ambient light, and provides an image having a generally greenish glow that enables the user to see his surroundings.
- the NVG is often mounted on a soldier's helmet and is movable between an operational position in front of the soldier's eyes, and a stowed position, such as above the soldier's eyes.
- a stowed position such as above the soldier's eyes.
- the eyepieces are generally directed outward, away from the soldier, and it may be possible for an enemy to see the green glow from the eyepieces, thus giving away the soldier's position.
- magnets have been incorporated in the helmet is mount so that, when the NVG is in its use position, the magnetic field generated by the magnet activates a magnetically operable switchpot, turning the NVG “ON”. When the NVG is flipped to is stowed position, the magnet slides within its housing away from the magnetic switchpot, removing the magnetic field, and turning the NVG “OFF”.
- problems exist with this technology When the soldier is not looking in a level direction, but is looking up or down, the magnet may inadvertently slide to the “OFF” position, rendering the NVG inoperable at an inopportune time. Additionally, if the soldier is rolling or tumbling, the magnet may again slide to the “OFF” position. Further, the magnet slides within its housing with an audible “click” that may disturb soldiers fearful of generating any sound whatsoever that may give away their position to the enemy.
- the present invention provides a night vision device.
- the device includes a housing that houses an intensifier tube and a proximity sensor mounted on the housing.
- An ON/OFF switch is operatively coupled to the intensifier tube and to the proximity sensor such that operation of the ON/OFF switch to the “ON” position automatically activates the proximity sensor.
- the present invention provides a method of operating a night vision device.
- the device comprises a housing that houses an intensifier tube and a proximity sensor mounted on the housing.
- An ON/OFF switch is operatively coupled to the intensifier tube and to the proximity sensor.
- the method comprises the step of turning only the ON/OFF switch to the ON position and activating both the intensifier tube and the proximity sensor.
- the present invention provides a method of operating a night vision device.
- the device comprises a device housing that houses an intensifier tube and a proximity sensor mounted on the device housing.
- An ON/OFF switch is operatively coupled to the intensifier tube and to the proximity sensor.
- the method comprises the steps of mounting the night vision device on a support; turning the ON/OFF switch to the ON position; moving the proximity sensor to a close proximity of a body to activate the intensifier tube; and removing the proximity sensor from a close proximity of the body to deactivate the intensifier tube.
- the present invention provides a night vision assembly comprising a support structure and a night vision device mounted on the support structure.
- the night vision device comprises a device housing that houses an intensifier tube and a proximity sensor mounted on the device housing.
- the proximity sensor is operatively coupled to the intensifier tube.
- An ON/OFF switch is operatively coupled to the intensifier tubes and to the proximity sensor such that operation of the ON/OFF switch to the “ON” position automatically activates the proximity sensor.
- FIG. 1 is a schematic view of a night vision device with proximity sensor according to a first embodiment of the present invention in a “use” position.
- FIG. 2 is a schematic view of the night vision device with proximity sensor in a “stowed” position.
- FIG. 3 is a perspective view of the night vision device with proximity sensor.
- FIG. 4 is an electrical schematic of the proximity sensor used in the night vision device.
- FIG. 5 is a perspective view of a night vision device with proximity sensor according to a second embodiment of the present invention, with the night vision device mounted on a rifle.
- a night vision device according to the several embodiments of the present invention is disclosed.
- the device includes a proximity sensor comprised of an infrared emitter and detector assembly that is used to detect when the night vision device is in close proximity to a user.
- the proximity sensor allows the night vision device to operate, but when the night vision device is outside of the predetermined range, the proximity sensor will not allow the night vision device to operate.
- the night vision device 100 is preferably mounted on a support bracket 40 that is fixed to a helmet 50 of a user 52 , such as a soldier.
- the support bracket 40 preferably includes a pivoting mount 42 that allows the user 52 to move the night vision device 100 between a first position, when the night vision device 100 is aligned for use with the eyes 54 of the user 52 , and a second position, shown in FIG. 2 , when the night vision device 100 is moved away from the eyes 54 of the user 52 in a non-use, or stowed, position.
- a common location of the second position is above the eyes 54 of the user 52 , toward the top of the head of the user 52 .
- the night vision device 100 includes a housing 102 that houses intensifier tubes 104 that are used to intensify the image being observed through the device 100 .
- intensifier tubes 104 are used, making the night vision device 100 a binocular device.
- those skilled in the art will recognize that only one intensifier tube 104 need be used, making the device a monocular device. Such a monocular device is described below with reference to a night vision device 200 .
- the housing 102 also has a rear portion 106 that faces the user 52 and a front portion 108 that faces away from the user 52 .
- the intensifier tubes 104 enable the user 52 to see objects in a low light environment, such as in a darkened room or at night.
- the intensifier tubes 104 are powered by a power source 110 .
- the power source is a single 1.5 volt DC battery, although those skilled in the art will recognize that any number of batteries and other voltages may be used.
- a main ON/OFF/VARIABLE GAIN switchpot 114 provides an electrical connection between the power source 110 and the intensifier tubes 104 and varies the gain of the intensifier tubes 104 . While an ON/OFF/VARIABLE GAIN switchpot 114 is desired, those skilled in the art will recognize that an ON/OFF switch may be used instead.
- a separate ON/OFF/MOMENTARY ON switch 112 operates to either turn an infrared LED ON, OFF, or MOMENTARY ON to provide illumination for the night vision device 100 in extremely low light conditions.
- a proximity sensor 120 is also mounted on the housing 102 . As shown in FIG. 3 , the proximity sensor 120 is mounted on the rear portion 106 of the housing 102 .
- the proximity sensor 120 is comprised of an infrared emitter 122 and a corresponding infrared detector 124 that is tuned to pick up the particular wavelength of light that is emitted from the infrared emitter 122 .
- the proximity sensor 120 When the night vision device 100 is in the first, or use, position, as shown in FIG. 1 , the proximity sensor 120 is activated, sending an output signal to the intensifier tubes 104 , to turn the intensifier tubes 104 on. When the intensifier tubes 104 are on, the intensifier tubes 104 emit a greenish glow that, in a darkened environment, can be seen over a great distance. However, the proximity sensor 120 ensures that the intensifier tubes 104 only emit the glow when the night vision device 100 is in the first position and the glow is directed into the user's eyes 54 . When the night vision device 100 is in the second, or stowed, position, as shown in FIG. 2 , the proximity sensor 120 is deactivated, and the output signal is not sent to the intensifier tubes 104 . The intensifier tubes 104 , therefore, turn off, and the greenish glow is not emitted from the intensifier tubes 104 .
- the proximity sensor 120 is comprised of the infrared emitter 122 and the infrared detector 124 , as well as an adjustment potentiometer (“pot”) 126 that adjusts the sensitivity of the proximity sensor 120 .
- the infrared emitter 122 emits a low power infrared signal that must be detected by the infrared detector 124 in order to activate the intensifier tubes 104 .
- the infrared emitter 122 may be an LED or any other suitable source for emitting infrared light.
- the infrared emitter 122 emits an infrared light having a wavelength of at least 900 nm.
- the infrared detector 124 is tuned to detect light waves that are transmitted at the infrared emitter wavelength.
- the operational threshold of the proximity sensor 120 is set by adjustment of the adjustment pot 126 . Once the appropriate operational threshold is determined, based on the required sensing range and types of reflective surfaces applicable to the anticipated usage scenarios, the adjustment pot 126 may optionally be eliminated in production units and replaced with a fixed resistor (not shown).
- An optical filter may optionally be included in front or, or as part of the infrared detector 124 to further tune the sensitivity of the infrared detector 124 to match the infrared emitter 122 and to reject ambient light at extraneous wavelengths.
- the infrared emitter 122 can be modulated or pulsed “ON” and “OFF”, and the circuit comprising the proximity sensor 120 can be arranged to be sensitive to this modulation or pulsing pattern in order to reduce the required power, improve the sensitivity, and/or better reject the interference of ambient light.
- input power of approximately 2.7 volts (nominal) powers the infrared emitter 122 .
- a voltage step up 128 steps up the voltage from 1.5 volts to about 2.7 volts to operate the proximity sensor 120 and the intensifier tubes 104 .
- the power is provided to the infrared emitter 122 through activation of the ON/OFF/VARIABLE GAIN switchpot 114 .
- the ON/OFF/VARIABLE GAIN switchpot 114 provides direct power to both the intensifier tubes 104 as well as the proximity sensor 120 , without the need for a separate ON/OFF/VARIABLE GAIN switchpot for the proximity sensor 120 .
- FIG. 4 shows the infrared emitter 122 supplied with a fixed operating power.
- the power to the infrared emitter 122 may alternatively be reduced in response to the level of detected power in order to reduce the infrared signature and power consumption of the proximity sensor 120 .
- the infrared light emitted from the infrared emitter 122 impinges on a reflective surface, such as the wearer's forehead 56 or the helmet 50 .
- the infrared light impinges on only a small area, such as approximately 100 mm 2 or less.
- the infrared light reflects from the surface 50 , 56 and is detected by the infrared detector 124 .
- the infrared detector 124 is sufficiently sensitive to be able to detect the reflected infrared light from a range of approximately 76.2 mm (3 inches) from the reflective surface 50 , 56 to the infrared detector 124 . Therefore, when the night vision device 100 is in the use position, the infrared detector 124 easily picks up the infrared light, allowing the intensifier tubes 104 to be powered up.
- the night vision device 100 When the night vision device 100 is pivoted about the pivoting mount 42 to the stowed position, as shown in FIG. 2 , the infrared light emitted from the infrared emitter 122 does not impinge upon any surface, resulting in the infrared light not being detected by the infrared detector 124 . Since the infrared detector 124 does not detect the infrared light signal, the intensifier tubes 104 will not power up. Since the intensifier tubes 104 are not powered up, the distinctive green glow will not be emitted from the intensifier tubes 104 .
- the infrared signal will drop below an operational threshold. If the infrared signal drops below that threshold for a predetermined period of time, such as about 0.1 second, the intensifier tubes 104 turn off. If the device 100 is then moved back to the use position, the infrared detector 124 will reacquire the infrared signal as the infrared signal reflects from the user's forehead 56 or the helmet 50 to the infrared detector 124 , allowing the intensifier tubes 104 to turn back on. Preferably, the time from reacquisition of the infrared signal to full power up of the intensifier tubes 104 is about 0.1 second.
- a night vision device 200 is mounted on a rifle 210 . While the night vision device 100 is shown as binoculars, the night vision device 200 shown in FIG. 5 is shown as a monocular scope. Further, while the night vision device 200 is shown mounted on the rifle 210 , those skilled in the art will recognize that the night vision device 200 may be mounted on a handgun, a rocket launcher, or any other suitable firearm.
- the night vision device 200 includes a proximity sensor 220 that operates in the same manner as proximity sensor 120 on the night vision device 100 described above, except that, instead of moving the night vision device 100 toward the user's face by pivoting the night vision device 100 about a support structure to activate the proximity sensor 120 , to activate the night vision device 200 , the user moves the rifle 210 and the night vision device 200 up to the user's face to activate the proximity sensor 220 .
- the night vision device 100 is described as being used with the helmet 52 and the night vision device 200 is described as being used with the rifle 210 , those skilled in the art will recognize that the night vision device 100 may alternately be used in other environments, such as mounted in an aircraft cockpit, or hand-held, without departing from the scope of the present invention.
- proximity sensors 120 , 220 are shown and described as infrared detectors, those skilled in the art will recognize that other types of detectors, such as ultrasonic, microwave, radio wave, millimeter wave, terahertz wave, and ultraviolet wave detectors, may be used in place of the infrared detector.
